# Qdrant Retrieve MCP Server

MCP server for semantic search with Qdrant vector database.

## Features

- Semantic search across multiple collections
- Multi-query support
- Configurable result count
- Collection source tracking

**Note**: The server connects to a Qdrant instance specified by URL. 

**Note 2**: The first retrieve might be slower, as the MCP server downloads the required embedding model.

## API

### Tools

- **qdrant_retrieve**
  - Retrieves semantically similar documents from multiple Qdrant vector store collections based on multiple queries
  - Inputs:
    - `collectionNames` (string[]): Names of the Qdrant collections to search across
    - `topK` (number): Number of top similar documents to retrieve (default: 3)
    - `query` (string[]): Array of query texts to search for
  - Returns:
    - `results`: Array of retrieved documents with:
      - `query`: The query that produced this result
      - `collectionName`: Collection name that this result came from
      - `text`: Document text content
      - `score`: Similarity score between 0 and 1
